WindowGroupProtocol

public protocol WindowGroupProtocol : ObjectProtocol

A GtkWindowGroup restricts the effect of grabs to windows in the same group, thereby making window groups almost behave like separate applications.

A window can be a member in at most one window group at a time. Windows that have not been explicitly assigned to a group are implicitly treated like windows of the default window group.

GtkWindowGroup objects are referenced by each window in the group, so once you have added all windows to a GtkWindowGroup, you can drop the initial reference to the window group with g_object_unref(). If the windows in the window group are subsequently destroyed, then they will be removed from the window group and drop their references on the window group; when all window have been removed, the window group will be freed.

The WindowGroupProtocol protocol exposes the methods and properties of an underlying GtkWindowGroup instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see WindowGroup. Alternatively, use WindowGroupRef as a lighweight, unowned reference if you already have an instance you just want to use.

  • ptr

    Untyped pointer to the underlying GtkWindowGroup instance.

    Declaration

    Swift

    var ptr: UnsafeMutableRawPointer! { get }
  • window_group_ptr Default implementation

    Typed pointer to the underlying GtkWindowGroup instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the GtkWindowGroup instance.

    Declaration

    Swift

    var window_group_ptr: UnsafeMutablePointer<GtkWindowGroup>! { get }
  • Required Initialiser for types conforming to WindowGroupProtocol

    Declaration

    Swift

    init(raw: UnsafeMutableRawPointer)
